Description

Technical Field

[0001] The invention belongs to the technical field of sheet metal processing, and in particular relates to a sheet metal trimming device. Background Art

[0002] Sheet metal refers to thin metal sheets processed by stamping, shearing, bending and other processes. Common materials include steel, aluminum, copper, etc. Sheet metal can be processed into a variety of shapes: flat shapes: such as flat plates and shields; bent shapes: such as boxes and brackets; punched shapes: plates with holes; formed shapes: such as cylinders and grooves. It is widely used in the automotive, aerospace, construction, electronics and other fields. It is mainly used to manufacture structural parts such as shells, casings, and brackets. Due to its light weight, high strength and easy forming characteristics, sheet metal occupies an important position in modern industry.

[0003] After the sheet metal is processed into a cylindrical shape, warping and burrs will appear on its edges. In order to avoid damage to other parts in subsequent processing and to make the appearance of the sheet metal more beautiful, further trimming is usually required. The existing trimming of cylindrical sheet metal is usually performed by automatic trimming by mechanical equipment. The cylindrical sheet metal is put on a rotating drum with the opening of the cylindrical sheet metal facing downward, and it is fixed by a fixing mechanism. During trimming, the rotating drum rotates and the cutting knife is used to trim it. Although this method can achieve fast trimming, each loading and unloading is done manually, the labor cost is high and the processing efficiency is low. At the same time, burrs will be left on the cut after each trimming, which requires additional grinding, which greatly reduces the processing efficiency of the sheet metal. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a sheet metal trimming device.

[0005] The technical solution adopted to solve the above technical problems is: a sheet metal trimming device, comprising a processing table, a loading rack is fixedly connected to the top center of the processing table, a feeding mechanism is fixedly installed on the top of the processing table near the bottom of the loading rack, and a pushing mechanism is fixedly installed on one side of the top of the processing table;

[0006] A fixing plate is fixedly connected to the other side of the top of the processing table, a fixing mechanism is installed on the fixing plate, a support frame is fixedly connected to the top of the processing table near the rear end of the fixing plate, a limit plate is fixedly connected to the top of the processing table near the rear end of the support frame, and a trimming mechanism is fixedly installed on the support frame;

[0007] A cutting mechanism is fixedly installed on the top of the processing table near the front end of the fixing mechanism, a pulling mechanism is fixedly installed on the top of the processing table near the rear end of the fixing mechanism, and a pushing mechanism is fixedly installed on the other side of the top of the processing table;

[0008] A first lower hopper is provided at the bottom of the processing table near the bottom of the fixing mechanism, a second lower hopper is provided at the bottom of the processing table near the bottom of the pulling mechanism, a baffle is fixedly connected to the top of the processing table near the top of the first lower hopper, and a plurality of cylindrical sheet metals are provided on the loading rack.

[0009] Furthermore, the feeding mechanism includes a first fixed seat fixedly connected to the top of the processing table near the bottom of the loading rack, a first cylinder is fixedly installed on the first fixed seat, a front end of the first cylinder piston is fixedly connected to a connecting pipe, a front end of the connecting pipe is fixedly connected to an arc-shaped feeding seat, the connecting pipe is slidably connected to the loading rack, and the arc-shaped feeding seat is located at the bottom of the front end of the loading rack.

[0010] Through the above technical scheme, when feeding and trimming cylindrical sheet metal, several cylindrical sheet metals are placed on the loading rack, and automatically rolled to the front bottom outlet of the loading rack by gravity, and then rolled onto the arc-shaped feeding seat, and the first cylinder is started, and the connecting pipe and the arc-shaped feeding seat are pushed by the piston to push the cylindrical sheet metal on the arc-shaped feeding seat to the horizontal end of the fixing mechanism, and then the cylindrical sheet metal is sleeved on the fixing mechanism in conjunction with the pushing mechanism. When the arc-shaped feeding seat is extended, the connecting pipe abuts against the next cylindrical sheet metal. When the arc-shaped feeding seat is reset, the next cylindrical sheet metal rolls into the arc-shaped feeding seat, so that the loading rack reciprocates to feed several cylindrical sheet metals. The mechanism automatically realizes the feeding process without the need for manual operation by the staff, which not only saves time and effort, but also greatly improves the trimming efficiency of the cylindrical sheet metal.

[0011] Furthermore, the pushing mechanism includes a second fixed seat fixedly connected to one side of the top of the processing table, a second cylinder is fixedly installed on the second fixed seat, one end of the second cylinder piston is fixedly connected to a connecting head, and the other end of the connecting head is rotatably connected to a push cylinder.

[0012] Through the above technical scheme, when the cylindrical sheet metal is sent to the horizontal end position of the fixed mechanism through the arc-shaped feeding seat, the second cylinder is started, and the connecting head is pushed by the piston, thereby pushing the push cylinder, and then quickly pushing the cylindrical sheet metal, so that the cylindrical sheet metal is sleeved on the fixed mechanism and fits with the cylindrical sheet metal, so that the cylindrical sheet metal can be subsequently rotated and trimmed. The mechanism has a compact structure and simple working steps, and thus has high processing efficiency for the cylindrical sheet metal.

[0013] Furthermore, the fixing mechanism includes a fixing sleeve arranged on the fixing plate, one end of the fixing sleeve is fixedly connected to an inner ring seat, a plurality of limiting holes are opened on the inner ring seat, a bearing is installed on the outer wall of the fixing sleeve, a gear ring is fixedly connected to the outer wall of the fixing sleeve near the other side of the bearing, one end of the inner ring seat is located at a position corresponding to the limiting hole and is fixedly connected to a first spring, a plurality of limiting holes are slidably connected to limiting rods, the other ends of a plurality of limiting rods are fixedly connected to a connecting circular plate, the other end of the connecting circular plate is fixedly connected to a connecting sleeve, a limiting ring is fixedly connected to the center of the connecting sleeve, the other end of the connecting sleeve is fixedly connected to a mold, a first motor is fixedly installed on the top of the processing table near the other side of the fixing plate, and a first gear is fixedly connected to the outer wall of the output shaft of the first motor.

[0014] Through the above technical scheme, when the cylindrical sheet metal is sleeved on the mold and the cylindrical sheet metal is rotated, the first motor is started, and the first gear is driven to rotate through the output shaft, thereby driving the meshing gear ring to rotate, and then driving the fixed sleeve to rotate. Since multiple limit rods are inserted into the corresponding limit holes and drive the connecting circular plate, the connecting sleeve and the mold to rotate, the cylindrical sheet metal on the mold is squeezed and fitted by the push cylinder at this time, so that the rotation of the cylindrical sheet metal is realized, which is convenient for the subsequent trimming mechanism to trim it. After the trimming is completed, when the incision needs to be polished, the push cylinder is continued to be pushed to extrude the cylindrical sheet metal and the mold, so that the mold is contracted through multiple first springs and contracted to the specified position, so that the subsequent trimming mechanism can polish it. After the polishing is completed, each part is reset and the next cylindrical sheet metal is processed.

[0015] Furthermore, the bearing is mounted on a fixed plate, the other ends of the plurality of first springs are fixedly connected to a connecting circular plate, the connecting circular plate is slidably connected to a fixed sleeve, and the gear ring is meshed with the first gear.

[0016] Through the above technical solution, when the mold contracts and extends, the connecting circular plate slides in the fixed sleeve, which greatly improves the stability of the mold when moving.

[0017] Furthermore, the trimming mechanism includes a hydraulic cylinder fixedly connected to the top of the support frame, the bottom end of the hydraulic cylinder piston is fixedly connected to the mounting frame, the bottom of the mounting frame is fixedly installed with a second motor, the outer wall of the output shaft of the second motor is fixedly connected to the second gear, one side of the mounting frame is rotatably connected to a rotating shaft, one end of the outer wall of the rotating shaft is fixedly connected to a third gear, the second gear is meshed with the third gear, the center of the outer wall of the rotating shaft is fixedly connected to a first fixing ring, the outer wall of the rotating shaft is detachably connected to a second fixing ring on a side close to the first fixing ring, a grinding wheel is installed on the outer wall of the rotating shaft between the first fixing ring and the second fixing ring, a trimming knife is installed on the other side of the outer wall of the rotating shaft close to the second fixing ring, a fixing head is installed on the other side of the outer wall of the rotating shaft close to the trimming knife, and a plurality of fixing bolts are installed between the first fixing ring, the second fixing ring, the grinding wheel, the trimming knife and the fixing head.

[0018] Through the above technical solution, when trimming the cylindrical sheet metal, the hydraulic cylinder is started, and the mounting frame is driven to slide on the limit plate through the piston, thereby pushing the grinding wheel and the trimming knife. At the same time, the second motor is started, and the second gear is driven to rotate through the output shaft, thereby driving the third gear to rotate, and then driving the rotating shaft to rotate, so that the rotation of the rotating shaft drives the grinding wheel and the trimming knife to rotate. When the trimming knife is pushed to contact the edge of the outer wall of the cylindrical sheet metal, the trimming of the cylindrical sheet metal is achieved. When the incision is ground, the cylindrical sheet metal contracts by a specified amount through the fixing mechanism. The hydraulic cylinder drives the grinding wheel and the trimming knife to move upward a certain distance, and then pushes the grinding wheel to contact the incision of the cylindrical sheet metal through the hydraulic cylinder. Since the diameter of the grinding wheel is larger than the trimming knife, the trimming knife does not contact the incision of the cylindrical sheet metal at this time, so the incision of the cylindrical sheet metal is ground, and there is no need to add grinding steps later. This not only improves the processing efficiency, but also improves the trimming quality. Subsequently, multiple fixing bolts can be disassembled to remove the second fixing ring, grinding wheel, trimming knife and fixing head, and then the grinding wheel and trimming knife can be replaced.

[0019] Furthermore, the cutting mechanism includes a third fixed seat fixedly connected to the top of the processing table near the front end of the connecting sleeve, the rear end of the third fixed seat is fixedly connected to the mounting sleeve, a second spring is fixedly connected inside the mounting sleeve, one end of the second spring is fixedly connected to the cutting base, the cutting base is slidably connected to the mounting sleeve, a third cylinder is fixedly installed on one side of the third fixed seat, and a cutting knife is fixedly connected to the rear end of the third cylinder piston.

[0020] Through the above technical solution, the metal ring after the cylindrical sheet metal is trimmed falls on the cutting base. At this time, the third cylinder is started, and the cutting knife is pushed by the piston, so that the cutting knife quickly contacts the cutting base and cuts the metal ring, which is convenient for discharging. It does not affect the normal processing of multiple cylindrical sheet metals by the equipment, and the equipment automatically discharges waste without manual operation, which greatly improves the processing efficiency. When the mold shrinks, it drives the cutting base, so that the cutting base shrinks through the second spring, which does not affect the operation of each part.

[0021] Furthermore, the pulling mechanism includes a fourth fixed seat fixedly connected to the top of the processing table near the rear end of the connecting sleeve, a fourth cylinder is fixedly installed on the fourth fixed seat, a front end of the fourth cylinder piston is fixedly connected to a pulling hook, and the metal ring after the cylindrical sheet metal is trimmed falls on the pulling hook.

[0022] Through the above technical solution, after the metal ring is cut off, the fourth cylinder is started, and the pulling hook is contracted by the piston to pull the metal ring. Since the incision of the metal ring is small, when it contacts the outer wall of the connecting sleeve, the incision is enlarged, so that the metal ring falls into the second lower hopper by gravity, which is convenient for its collection. The mechanism automatically discharges waste and automatically collects the processed cylindrical sheet metal and remaining waste, making the overall processing steps compact and efficient.

[0023] Furthermore, the ejection mechanism includes a fifth fixed seat fixedly connected to the other side of the top of the processing table, a fifth cylinder is fixedly installed on the top of the fifth fixed seat, and one end of the fifth cylinder piston is fixedly connected to a ejector rod.

[0024] Through the above technical solution, after the cylindrical sheet metal is trimmed, when it is necessary to unload the material, the fifth cylinder is started, and the push rod is pushed by the piston, so that one end of the push rod pushes the cylindrical sheet metal, and the cylindrical sheet metal is pushed into the first unloading hopper for easy collection. There is no need for staff to manually take the unloading, which is highly efficient.

[0025] Furthermore, the push rod is slidably connected to the inner ring seat and the limiting ring.

[0026] Through the above technical solution, the connecting sleeve and the limiting ring slide with the push rod during extension and rotation, and do not affect the normal extension and retraction of the push rod.

[0027] The beneficial effects of the present invention are as follows: (1) The present invention designs a fixing mechanism and a trimming mechanism. After trimming the cylindrical sheet metal, the fixing mechanism is retracted by a specified distance, and then the hydraulic cylinder drives the grinding wheel to contact the cut of the cylindrical sheet metal to achieve cutting and grinding of the cut of the cylindrical sheet metal. The cylindrical sheet metal is immediately polished after trimming, and there is no need to add a grinding step later. This not only improves the processing efficiency, but also improves the trimming quality. (2) The present invention designs a feeding mechanism, a pushing mechanism and a pushing mechanism. The device automatically feeds, pushes and pushes the cylindrical sheet metal after trimming. There is no need for manual operation by the staff. The structures of each mechanism are compact, which greatly improves the trimming efficiency of the cylindrical sheet metal. (3) The present invention designs a cutting mechanism and a pulling mechanism. After trimming the cylindrical sheet metal each time, the cutting mechanism cuts the remaining metal ring, and then the pulling mechanism enlarges the cut of the metal ring, so that the metal ring can be automatically unloaded. There is no need for the staff to manually clean up the waste. This not only reduces the labor cost, but also greatly improves the processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The connecting pipe 303 and the arc-shaped feeding seat 304 are pushed by the piston to push the cylindrical sheet metal 16 on the arc-shaped feeding seat 304 to the horizontal end of the fixing mechanism 6, and then the pushing mechanism 4 is cooperated to put the cylindrical sheet metal 16 on the fixing mechanism 6. When the arc-shaped feeding seat 304 is extended, the connecting pipe 303 is against the next cylindrical sheet metal 16. When the arc-shaped feeding seat 304 is reset, the next cylindrical sheet metal 16 rolls into the arc-shaped feeding seat 304, so that the loading rack 2 reciprocates to feed several cylindrical sheet metals 16. The mechanism automatically realizes the feeding process without manual operation of the staff, which not only saves time and effort, but also greatly improves the efficiency of trimming the cylindrical sheet metal 16.

[0042] like Figure 1-Figure 3 As shown, a pushing mechanism 4 is fixedly installed on one side of the top of the processing table 1, and the pushing mechanism 4 includes a second fixed seat 401 fixedly connected to one side of the top of the processing table 1, and a second cylinder 402 is fixedly installed on the second fixed seat 401. One end of the piston of the second cylinder 402 is fixedly connected to a connecting head 403, and the other end of the connecting head 403 is rotatably connected to a push cylinder 404. When the cylindrical sheet metal 16 is sent to the horizontal end position of the fixing mechanism 6 through the arc-shaped feeding seat 304, the second cylinder 402 is started, and the connecting head 403 is pushed by the piston, thereby pushing the push cylinder 404, and then quickly pushing the cylindrical sheet metal 16, so that the cylindrical sheet metal 16 is sleeved on the fixing mechanism 6 and fits with the cylindrical sheet metal 16, so that the cylindrical sheet metal 16 can be rotated and trimmed later. The mechanism has a compact structure and simple working steps, and thus has high processing efficiency for the cylindrical sheet metal 16.

[0043] like Figure 1-Figure 8As shown, a fixing plate 5 is fixedly connected to the other side of the top of the processing table 1, and a fixing mechanism 6 is installed on the fixing plate 5. The fixing mechanism 6 includes a fixing sleeve 601 arranged on the fixing plate 5, and an inner ring seat 602 is fixedly connected to one end of the fixing sleeve 601, and a plurality of limiting holes 603 are opened on the inner ring seat 602. A bearing 604 is installed on the outer wall of the fixing sleeve 601, and a gear ring 605 is fixedly connected to the other side of the outer wall of the fixing sleeve 601 near the bearing 604. One end of the inner ring seat 602 is located at a position corresponding to the limiting hole 603 and is fixedly connected to a first spring 606. The plurality of limiting holes 603 The inner and outer ends of the plurality of limit rods 607 are all slidably connected to limit rods 607, the other ends of the plurality of limit rods 607 are all fixedly connected to a connecting circular plate 608, the other ends of the connecting circular plate 608 are fixedly connected to a connecting sleeve 609, the inner center of the connecting sleeve 609 is fixedly connected to a limit ring 610, the other end of the connecting sleeve 609 is fixedly connected to a mold 611, a first motor 612 is fixedly installed on the other side of the top of the processing table 1 close to the fixed plate 5, the outer wall of the output shaft of the first motor 612 is fixedly connected to a first gear 613, when the cylindrical sheet metal 16 is sleeved on the mold 611, the first motor is started when the cylindrical sheet metal 16 is rotated. The machine 612 drives the first gear 613 to rotate through the output shaft, thereby driving the meshing gear ring 605 to rotate, and then driving the fixed sleeve 601 to rotate. Since multiple limiting rods 607 are inserted into the corresponding limiting holes 603, and drive the connecting circular plate 608, the connecting sleeve 609 and the mold 611 to rotate, at this time, the cylindrical sheet metal 16 on the mold 611 is squeezed and fitted by the push cylinder 404, so that the cylindrical sheet metal 16 can be rotated, which is convenient for the subsequent trimming mechanism 9 to trim it. After the trimming is completed, when the incision needs to be polished, the push cylinder 404 is continued to be pushed to extrude the cylindrical sheet metal 16 and the mold 611, so that The mold 611 is contracted by multiple first springs 606 and contracted to a specified position, so that the subsequent trimming mechanism 9 can grind it. After grinding, each part is reset and the next cylindrical sheet metal 16 is processed. The bearing 604 is installed on the fixed plate 5. The other end of the multiple first springs 606 is fixedly connected to the connecting circular plate 608, and the connecting circular plate 608 is slidably connected to the fixed sleeve 601. The ring gear 605 is meshed with the first gear 613. When the mold 611 contracts and extends, the connecting circular plate 608 slides in the fixed sleeve 601, which greatly improves the stability of the mold 611 when moving.

[0044] like Figure 1-Figure 11As shown, a support frame 7 is fixedly connected to the top of the processing table 1 near the rear end of the fixed plate 5, a limiting plate 8 is fixedly connected to the top of the processing table 1 near the rear end of the support frame 7, a trimming mechanism 9 is fixedly installed on the support frame 7, and the trimming mechanism 9 includes a hydraulic cylinder 901 fixedly connected to the top of the support frame 7, a mounting frame 902 is fixedly connected to the bottom end of the piston of the hydraulic cylinder 901, a second motor 903 is fixedly installed on the bottom of the mounting frame 902, a second gear 904 is fixedly connected to the outer wall of the output shaft of the second motor 903, a rotating shaft 905 is rotatably connected to one side of the mounting frame 902, and a third gear 906 is fixedly connected to one end of the outer wall of the rotating shaft 905. The second gear 904 is connected to the The third gear 906 is meshed, and a first fixing ring 907 is fixedly connected to the center of the outer wall of the rotating shaft 905. A second fixing ring 908 is detachably connected to the outer wall of the rotating shaft 905 near the first fixing ring 907. A grinding wheel 909 is installed between the outer wall of the rotating shaft 905 near the first fixing ring 907 and the second fixing ring 908. A trimming knife 910 is installed on the other side of the outer wall of the rotating shaft 905 near the second fixing ring 908. A fixing head 911 is installed on the other side of the outer wall of the rotating shaft 905 near the trimming knife 910. A plurality of fixing members are installed between the first fixing ring 907, the second fixing ring 908, the grinding wheel 909, the trimming knife 910 and the fixing head 911. The fixing bolt 912 is fixed. When trimming the cylindrical sheet metal 16, the hydraulic cylinder 901 is started, and the mounting frame 902 is driven to slide on the limit plate 8 through the piston, thereby pushing the grinding wheel 909 and the trimming knife 910. At the same time, the second motor 903 is started, and the second gear 904 is driven to rotate through the output shaft, thereby driving the third gear 906 to rotate, and then driving the rotating shaft 905 to rotate, so that the rotation of the rotating shaft 905 drives the grinding wheel 909 and the trimming knife 910 to rotate. When the trimming knife 910 is pushed to contact the edge of the outer wall of the cylindrical sheet metal 16, the trimming of the cylindrical sheet metal 16 is achieved. When grinding its incision, the cylindrical sheet metal 16 shrinks a specified distance through the fixing mechanism 6, and the hydraulic The pressure cylinder 901 drives the grinding wheel 909 and the trimming knife 910 to move upward a certain distance, and then pushes the grinding wheel 909 to contact the incision of the cylindrical sheet metal 16 through the hydraulic cylinder 901. Since the diameter of the grinding wheel 909 is larger than the trimming knife 910, the trimming knife 910 does not contact the incision of the cylindrical sheet metal 16 at this time, thereby achieving the grinding of the incision of the cylindrical sheet metal 16. There is no need to add further grinding steps later, which not only improves the processing efficiency, but also improves the trimming quality. Subsequently, multiple fixing bolts 912 can be disassembled to remove the second fixing ring 908, the grinding wheel 909, the trimming knife 910 and the fixing head 911, and then the grinding wheel 909 and the trimming knife 910 are replaced.

[0045] like Figure 1-Figure 9As shown, a cutting mechanism 10 is fixedly installed at the top of the processing table 1 near the front end of the fixing mechanism 6, and the cutting mechanism 10 includes a third fixing seat 1001 fixedly connected to the top of the processing table 1 near the front end of the connecting sleeve 609, and the rear end of the third fixing seat 1001 is fixedly connected to the mounting sleeve 1002, and a second spring 1003 is fixedly connected in the mounting sleeve 1002, and one end of the second spring 1003 is fixedly connected to a cutting base 1004, and the cutting base 1004 is slidably connected to the mounting sleeve 1002, and a third cylinder 1005 is fixedly installed on one side of the third fixing seat 1001, and the rear end of the piston of the third cylinder 1005 A cutting knife 1006 is fixedly connected, and the metal ring after trimming the cylindrical sheet metal 16 falls on the cutting base 1004. At this time, the third cylinder 1005 is started, and the cutting knife 1006 is pushed by the piston, so that the cutting knife 1006 quickly contacts the cutting base 1004 to cut the metal ring, which is convenient for discharging, and does not affect the normal processing of multiple cylindrical sheet metals 16 by the equipment. The equipment automatically discharges waste materials without manual operation, which greatly improves the processing efficiency. When the mold 611 shrinks, it drives the cutting base 1004, so that the cutting base 1004 shrinks through the second spring 1003, and does not affect the operation of each part.

[0046] like Figure 1-Figure 6 As shown, a pulling mechanism 11 is fixedly installed on the top of the processing table 1 near the rear end of the fixing mechanism 6, and the pulling mechanism 11 includes a fourth fixing seat 1101 fixedly connected to the top of the processing table 1 near the rear end of the connecting sleeve 609, and a fourth cylinder 1102 is fixedly installed on the fourth fixing seat 1101, and a pulling hook 1103 is fixedly connected to the front end of the piston of the fourth cylinder 1102. The metal ring of the cylindrical sheet metal 16 after trimming falls on the pulling hook 1103. After the metal ring is cut off, the fourth cylinder 1102 is started at this time, and the pulling hook 1103 is contracted by the piston to pull the metal ring. Since the incision of the metal ring is small, when it contacts the outer wall of the connecting sleeve 609, the incision is enlarged, so that the metal ring falls into the second lower hopper 14 by gravity, which is convenient for its collection. The mechanism automatically discharges waste and automatically collects the processed cylindrical sheet metal 16 and remaining waste, so that the overall processing steps are compact and efficient.

[0047] like Figure 1-Figure 7As shown, a feeding mechanism 12 is fixedly installed on the other side of the top of the processing table 1, a first lower hopper 13 is provided at the bottom of the processing table 1 near the bottom of the fixing mechanism 6, a second lower hopper 14 is provided at the bottom of the processing table 1 near the bottom of the pulling mechanism 11, a baffle 15 is fixedly connected to the top of the processing table 1 near the top of the first lower hopper 13, a plurality of cylindrical sheet metals 16 are provided on the loading rack 2, the feeding mechanism 12 includes a fifth fixed seat 1201 fixedly connected to the other side of the top of the processing table 1, a fifth cylinder 1202 is fixedly installed on the top of the fifth fixed seat 1201, and the fifth cylinder 1202 is movable One end of the plug is fixedly connected to a push rod 1203. After the cylindrical sheet metal 16 is trimmed, when it is necessary to unload the material, the fifth cylinder 1202 is started, and the push rod 1203 is pushed by the piston, so that one end of the push rod 1203 pushes the cylindrical sheet metal 16, and the cylindrical sheet metal 16 is pushed into the first unloading hopper 13 for easy collection. There is no need for staff to manually take the unloading, and the efficiency is high. The push rod 1203 is slidably connected to the inner ring seat 602 and the limit ring 610. The connecting sleeve 609 and the limit ring 610 slide with the push rod 1203 during extension and rotation, and does not affect the normal extension and retraction of the push rod 1203.

[0048] The working principle of this embodiment is as follows: the staff places several cylindrical sheet metals 16 on the loading rack 2, and the cylindrical sheet metals 16 are automatically rolled onto the arc-shaped feeding seat 304 by gravity. At this time, the first cylinder 302 is started, and the connecting pipe 303 and the arc-shaped feeding seat 304 are pushed by the piston to push the cylindrical sheet metal 16 on the arc-shaped feeding seat 304 to the horizontal end of the mold 611, and the second cylinder 402 is started, and the connecting head 403 is pushed by the piston, thereby pushing the push cylinder 404, and then quickly pushing the cylindrical sheet metal 16 on the arc-shaped feeding seat 304, so that the cylindrical sheet metal 16 is sleeved on the mold 611 and fits with the cylindrical sheet metal 16. At this time, the trimming position of the cylindrical sheet metal 16 is flush with the trimming knife 910;

[0049] When trimming the cylindrical sheet metal 16, the hydraulic cylinder 901 is started, and the mounting frame 902 is driven to slide on the limit plate 8 through the piston, thereby pushing the grinding wheel 909 and the trimming knife 910, and the second motor 903 is started at the same time, and the second gear 904 is driven to rotate through the output shaft, thereby driving the third gear 906 to rotate, and then driving the rotating shaft 905 to rotate, so that the rotation of the rotating shaft 905 drives the grinding wheel 909 and the trimming knife 910 to rotate, and the first motor 612 is started at the same time, and the first gear 613 is driven to rotate through the output shaft, and the meshing gear ring 605 is driven to rotate, thereby driving the mold 611 to rotate, and then driving the cylindrical sheet metal 16 to rotate. When the trimming knife 910 is pushed to contact the edge of the outer wall of the cylindrical sheet metal 16, the trimming of the cylindrical sheet metal 16 is achieved;

[0050] The trimmed metal ring falls on the cutting base 1004 and the material pulling hook 1103, and the third cylinder 1005 is started to push the cutting knife 1006 through the piston, so that the cutting knife 1006 quickly contacts the cutting base 1004 to cut the metal ring. At the same time, the fourth cylinder 1102 is started to contract the material pulling hook 1103 through the piston, thereby pulling the metal ring. Since the incision of the metal ring is small, when it contacts the outer wall of the connecting sleeve 609, the incision is enlarged, so that the metal ring falls into the second lower hopper 14 by gravity and is collected;

[0051] When grinding the cylindrical sheet metal 16 after trimming, the cylindrical sheet metal 16 is shrunk by a specified distance through the mold 611, so that the cut of the cylindrical sheet metal 16 is flush with the grinding wheel 909, and the grinding wheel 909 and the trimming knife 910 are driven by the hydraulic cylinder 901 to move upward for a certain distance, and then the grinding wheel 909 is pushed by the hydraulic cylinder 901 to contact the cut of the cylindrical sheet metal 16. Since the diameter of the grinding wheel 909 is larger than the trimming knife 910, the trimming knife 910 does not contact the cut of the cylindrical sheet metal 16 at this time, so that the cut of the cylindrical sheet metal 16 is ground;

[0052] After the cylindrical sheet metal 16 is cut and polished, the mold 611 drives the cylindrical sheet metal 16 to return to its initial position, and starts the fifth cylinder 1202, pushing the push rod 1203 through the piston, so that one end of the push rod 1203 pushes the cylindrical sheet metal 16, and pushes the cylindrical sheet metal 16 into the first lower hopper 13 for collection. The next cylindrical sheet metal 16 is loaded, pushed, trimmed, polished and collected according to the same principle.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
